Synthesis of TiO2Nanowires via Hydrothermal Method

Titanium dioxide (TiO 2 ) nanowires have been successfully synthesized by a simple, rapid, inexpensive, and novel approach based on a hydrothermal method. The use of hydrothermal treatment on TiO 2 nanopowder as a precursor with highly concentrated sodium hydroxide for 6 h produced a novel nanostructure of TiO 2 nanowires. The field-emission scanning electron microscopy (FESEM) image shows that the synthesized TiO 2 nanowires are very abundant in quantity with diameters ranging from 8.0–14 nm and are extra long. X-ray diffraction (XRD) result indicates that the synthesized TiO 2 nanowires are mainly composed of anatase phase with a minor of rutile phase. These properties of nanowires promise a broad range of applications in electronic devices.
